xDown

xDown is malware associated with the suspected Chinese-speaking threat actor IndigoZebra. Kaspersky’s 2017 reporting on IndigoZebra described a covert operation targeting former Soviet republics and associated the activity with malware including Meterpreter, Poison Ivy RAT, xDown, and xCaon. Check Point later referenced that same Kaspersky reporting while describing IndigoZebra espionage activity against political and government targets in Central Asia and Afghanistan. Based on the provided content, xDown is linked to IndigoZebra operations, but the specific capabilities, infection vector, command-and-control method, and indicators of compromise for xDown are not provided in the source material. High-confidence context indicates IndigoZebra targeted political entities and government organizations, including activity in Kyrgyzstan, Uzbekistan, and the Afghan government.
